After an assessment of all engineering data, engineers have determined that the Delta II second stage tank for STEREO is ready for processing to continue. A final determination of flightworthiness will be made prior to spacecraft mating to the Delta II rocket. The second stage will be re-erected atop the first stage on Friday, Sept. 29 at Pad 17-B.

STEREO remains at the Astrotech Space Operations Facility. During the hiatus, the spacecraft flight batteries were reconditioned. The twin solar observatories remain stacked on top of the third stage. The transportation canister will now be reinstalled in preparation for moving to the launch pad on Oct. 12.
